In the present embodiment, the body 1 includes the upper part 11, the bending part 13 and the lower part 12. The structures of the upper part 11 and the lower part 12 are substantially identical, and the difference is that electronic components 113 integrated inside the upper part 11 and the lower part 12 are different. The upper part 11 is now taken as an example for illustration, and a specific structure of the lower part 12 will not be described herein.

The upper part 11 includes a rectangular housing 111, a circuit board 112 and the electronic component 113, the electronic component 113 is integrated to the circuit board 112, and the circuit board 112 is fixedly disposed in the rectangular housing 111. The upper part 11 has a first upper end 11 a and a first lower end 11 b arranged opposite to each other, and a first surface 11 c and a second surface 11 d arranged opposite to each other. The first lower end 11 b defines a first opening so as to be electrically coupled to the lower part 12.

Preferably, referring to FIGS. 2 and 3, an end of the flexible circuit board 114 extends into the first opening and is electrically coupled to the circuit board 112 in the upper part 11, and the other end of the flexible circuit board 114 extends into the second opening and is electrically coupled to an interior of the lower part 12, so as to achieve electrical coupling between the upper part 11 and the lower part 12, such that the upper part 11 and the lower part 12 can form a whole, and bending performance of a bending area can also be improved. Certainly, in other embodiments, the flexible circuit board 114 may also be replaced by a flat cable.

Further, the bending part 13 may be a sheet made of materials which can be bent repeatedly and has elasticity. By providing the bending part 13 of a sheet structure to surfaces of the upper part 11 and the lower part 12, an open-close angle between the upper part 11 and the lower part 12 can range from 0 to 360 degrees. In this way, the bending part 13 has a simple structure, thus facilitating assembling of the foldable terminal 100.

Preferably, the bending part 13 is a soft metal sheet, thereby further enhancing bending durability of the foldable terminal 100.

Specifically, in order to further improve a flatness of the surface of the body 1, an outer surface of the bending part 13 is flush with the back surface 1 b of the body 1.

The bending part 13 resembles a strip, and includes an upper coupling section and a lower coupling section arranged opposite to each other.

As the bending part 13 has elasticity and is stretchable, the open-close angle between the upper part 11 and the lower part 12 ranges from 0 to 360 degrees.

In general, the foldable terminal 100 substantially has three bending states: in a first bending state A as illustrated in FIG. 1, the open-close angle between the upper part 11 and the lower part 12 is 180 degrees, and the foldable terminal 100 forms a linear shape; in a second bending state B as illustrated in FIG. 4, the open-close angle between the upper part 11 and the lower part 12 is 0 degree, the obverse surface 1 a of the body 1 is an inner bending surface when the foldable terminal 100 is bent; in a third bending state C as illustrated in FIG. 5, the open-close angle between the upper part 11 and the lower part 12 is 0 degree, the back surface 1 b of the body 1 is the inner bending surface when the foldable terminal 100 is bent. Certainly, in other embodiments, the bending part 13 may also be a silicone sheet, and the bending part 13 is adhered to the surfaces of the upper part 11 and the lower part 12.

The second magnetic attraction member 32 is fixedly disposed in the rectangular housing 111 of the lower part 12, adjacent to the second lower end 12 b, and adjacent to the third surface 12 c, i.e. adjacent to the flexible screen assembly 2.

When the foldable terminal 100 is bent into the second bending state B, a strong magnetic force is present between the first magnetic attraction member 31 and the second magnetic attraction member 32, the first magnetic attraction member 31 and the second magnetic attraction member 32 are attracted together, such that the upper part 11 can be tightly attached to the lower part 12, that is, a folding of the foldable terminal 100 can be achieved, to reduce a size of the foldable terminal 100, thereby facilitating carrying of the foldable terminal 100.

In general, both of the first magnetic attraction member 31 and the second magnetic attraction member 32 are made of magnets, such that coupling performance of the magnetic attraction assembly 3 can be further improved.

When the foldable terminal 100 is changed from the first bending state A to the second bending state B or the third bending state C, the user will realize that he/she is closing the foldable terminal 100 due to the repulsive force of the magnetic buffer assembly 4, so as to reduce the probability of damage to the foldable terminal 100 which is caused by a collision between the upper part 11 and the lower part 12 when the foldable terminal 100 is closed vigorously and inadvertently by the user, such that the reliability of the foldable terminal 100 is further improved.

Preferably, the first magnetic buffer member 41 and the second magnetic buffer member 42 are adhered to the upper part 11 and the lower part 12 correspondingly. In this arrangement, fixing of the magnetic buffer assembly 4 can be further simplified, and coupling strength between the magnetic buffer assembly 4 and the foldable terminal 100 can be improved.

In the present embodiment, preferably, in order to further reduce the influence of the magnetic attraction assembly 3 on other electronic components 113 in the housing of the foldable terminal 100, the ferromagnetic shielding member 5 includes two iron frame casings 51 and foam 52. One iron frame casing 51 is fitted in the other iron frame casing 51, the two iron frame casings 51 define a filling gap therebetween, and the foam 52 is clamped in the filling gap. Specifically, the two iron frame casings 51 have the same shape, the difference is that one of the two iron frame casings 51 is smaller, and the other is larger. Accordingly, the smaller iron frame casing 51 is disposed in the larger iron frame casing 51, and the filling gap for filling the foam 52 is formed between circumferential surfaces of the two iron frame casings 51. Preferably, in order to further enhance ferromagnetic shielding performance of the ferromagnetic shielding member 5, a wall thickness of the iron frame casing 51 is 0.5 mm, and the filling gap is 10 mm.

The four ferromagnetic shielding members 5 cover the first magnetic attraction member, the second magnetic attraction member, the first magnetic buffer member and the second magnetic buffer member correspondingly, so as to further reduce the influence of the magnetic attraction assembly 3 and the magnetic buffer assembly 4 on other electronic components 113 in the housing of the foldable terminal 100.

When the foldable terminal 100 is in use, the upper part 11 can be bent to 180 degrees (at least greater than 0 degree) relative to the lower part 12 by overcoming a magnetic attraction force between the first magnetic attraction member 31 and the second magnetic attraction member 32, and the foldable terminal 100 can be interacted with by clicking and touching the flexible screen assembly 2; when the foldable terminal 100 is not in use and the flexible screen assembly 2 of the foldable terminal 100 is not desired to be exposed, the foldable terminal 100 can be bought into the second bending state B, during the bending of the foldable terminal 100, the first magnetic buffer member 41 and the second magnetic buffer member 42 of the magnetic buffer assembly 4 repels each other to perform a fool-proof reminder for the user, and the repulsive force between the first magnetic buffer member 41 and the second magnetic buffer member 42 of the magnetic buffer assembly 4 is continued to be overcome to make the first magnetic attraction member 31 magnetically attracted to the second magnetic attraction member 32, such that the foldable terminal 100 is kept in the second bending state B; and when the foldable terminal 100 is not in use but the flexible screen assembly 2 of the foldable terminal 100 is desired to be exposed, the body 1 is bent to bring the foldable terminal 100 into the third bending state C.
